Indian Oil Corporation Sees Sharp Open Interest Surge Amid Mixed Market Signals

Open Interest and Volume Dynamics

On 20 Feb 2026, IOC’s open interest (OI) in derivatives rose sharply to 44,628 contracts from the previous 39,812, marking an increase of 4,816 contracts or 12.1%. This surge in OI was accompanied by a futures volume of 29,700 contracts, reflecting robust trading activity. The futures value stood at approximately ₹97,236 lakhs, while the options segment exhibited a substantial notional value of ₹15,591.6 crores, culminating in a total derivatives value exceeding ₹98,664 lakhs.

This spike in open interest, coupled with elevated volume, typically indicates fresh positions being established rather than existing ones being squared off. Market participants appear to be actively repositioning, possibly anticipating significant price movements in the near term.

Price Performance and Moving Averages

Despite the increased derivatives activity, IOC’s stock price has underperformed, declining by 0.59% on the day and falling 2.89% over the past two consecutive sessions. This contrasts with the sector’s 0.58% gain and the Sensex’s 0.62% rise, highlighting relative weakness in IOC’s equity performance.

Technically, the stock price remains above its 20-day, 50-day, 100-day, and 200-day moving averages, signalling a longer-term uptrend. However, it trades below the 5-day moving average, suggesting short-term selling pressure or consolidation. This divergence between short- and long-term moving averages often reflects market indecision or a pause before a potential directional move.

Investor Participation and Liquidity

Investor engagement has intensified, with delivery volume on 19 Feb reaching 86.26 lakh shares, a 44.8% increase compared to the five-day average delivery volume. This rising participation indicates that investors are not merely trading on a speculative basis but are also taking actual delivery positions, which can be a sign of conviction.

Liquidity remains adequate for sizeable trades, with the stock supporting a trade size of approximately ₹3.43 crores based on 2% of the five-day average traded value. This ensures that institutional and retail investors can execute orders without significant market impact.

Market Positioning and Directional Bets

The pronounced increase in open interest alongside rising volumes suggests that traders are actively building positions in IOC derivatives. Given the stock’s recent price softness and underperformance relative to the sector, this could indicate a mix of hedging activity and speculative directional bets.

Some market participants may be positioning for a potential rebound, as the stock remains above key long-term moving averages and offers a relatively high dividend yield of 4.6%, which is attractive in the current interest rate environment. Conversely, the short-term price weakness and the stock trading below its 5-day moving average may have prompted others to take protective short positions or employ option strategies to capitalise on expected volatility.

Overall, the derivatives market activity points to a nuanced outlook, with investors balancing between cautious optimism and risk management amid broader market uncertainties.

Fundamental and Market Context

Indian Oil Corporation Ltd, a large-cap oil sector heavyweight with a market capitalisation of ₹2,44,678.70 crores, continues to command strong investor interest. The company’s mojo score of 87.0 and an upgraded mojo grade to “Strong Buy” as of 2 Feb 2026 reflect robust fundamentals and positive analyst sentiment. This upgrade from a previous “Buy” rating underscores growing confidence in the company’s earnings prospects and strategic positioning within the oil industry.

Despite the recent price dip, IOC’s valuation metrics and dividend yield remain compelling for long-term investors. The stock’s ability to maintain levels above major moving averages suggests underlying strength, while the derivatives market activity signals that traders are actively recalibrating their exposure in anticipation of upcoming catalysts.

Implications for Investors

For investors and traders, the current scenario presents both opportunities and risks. The strong mojo grade upgrade to “Strong Buy” and the company’s solid fundamentals support a positive long-term outlook. However, the recent price weakness and short-term technical signals warrant caution.

Investors should closely monitor open interest trends and volume patterns in the derivatives market as these often presage significant price moves. The rising delivery volumes indicate genuine investor interest beyond speculative trading, which could provide a stabilising influence on the stock price.

Given the stock’s liquidity and sizeable market capitalisation, institutional investors can execute meaningful trades without undue price impact, making IOC a viable candidate for portfolio inclusion or rebalancing.

Conclusion

Indian Oil Corporation Ltd’s recent surge in open interest and trading volumes in the derivatives segment highlights a dynamic market environment with active repositioning by investors. While the stock has experienced short-term price softness, its strong fundamentals, attractive dividend yield, and upgraded mojo rating underpin a favourable medium- to long-term outlook.

Market participants should weigh the mixed technical signals and evolving derivatives positioning carefully, balancing potential upside against near-term volatility risks. Continued monitoring of open interest and volume trends will be crucial to gauge the prevailing market sentiment and directional bias for IOC shares.
